Good week of progress so far, I have on order the sealant to fix the remaining leaks in the chip boiler and have ordered the circulator pumps for to tie in the solar tank coil and the chip boiler. But to make progress toward completion I have to do more than sit in front of the computer writing about pump sizing and ordering materials. So time to get out the welder and add a good sized drain to the tank and create the ability to rotate the tank to make the sealant process successful. Pictures to follow.
On another note I am having trouble hooking up a 4 line LCD display, primarily because it seems to have different pinouts than a standard LCD and because it has two enable pins, one pin for each two lines. So more research is required on that.
